ASR9000s report altitude (admin show environ) . I have checked
CISCO-ENTITY-SENSOR-MIB and have not been able to see where I can poll
this number.
Anyone know how to poll?
I was under the impression that the altitude setting was manual, and was
intended to help the system vary the fan speeds in line with the
altitude.
There's something in the back of my brain about a bug wherein the fan
curve wasn't quite optimised for certain hardware configurations, and so
the workaround was to set the altitude to some higher number in order to
force the fan curve to step-up (which could also then blow your PSU
budget :))
But, this was all some time ago; perhaps it has changed in use?
